Is this really art?
Artist Caleb Larsen's A Tool to Deceive and Slaughter is an automated black box that perpetually attempts to sell itself on eBay every seven days. According to an agreement drafted by the artist, failure to comply with this, and almost 20 other rules, will invalidate the box as a work of art. So basically you buy it and then immediately have to put it up for auction again. The good news, I think, is that you get to keep the money from the second sale. Bidding starts at $2,500.
